Why should you wear protective motorcycle clothing with a high-visibility colouring?

You answered correctly. Wearing protective motorcycle clothing in bright, high-visibility colors helps other road users notice you more easily (answer 1). This increased visibility reduces the risk of being overlooked, which in turn lowers the likelihood of accidents (answer 2). The third answer, about being able to drive home if your lights fail, is incorrect; high-visibility clothing is no substitute for working lights at night or in poor visibility. Always use proper lighting and high-visibility gear together to maximize safety on the road.
